Description

The present invention relates to a portable information terminal with a lighting device having a function as a flashlight.

Mobile information terminals represented by mobile phones and PHS phones are widely spread and far exceed the penetration rate of fixed telephones in the past.

  Mobile phones and the like are known to exhibit unexpected effects in an emergency. For example, in the event of various accidents such as climbing or hiking, or in the event of an earthquake, flood or other disaster, it is easy to contact the outside world, making it easier to request rescues and announce location points. It is one of the indispensable tools.

By the way, the first thing people instinctively demand at the time of the disaster is the light in the dark. However, it is often the case that this light cannot be obtained at hand when it is liver and kidney. For example, even if you usually prepare emergency flashlights at the required places in your house, you may have forgotten where the emergency lights were prepared in the event of a disaster, or if the disaster is especially at night Inconveniences such as being difficult to find while knowing the location often occur.

  The best way to prevent such inconvenience is to always carry a flashlight or the like. However, putting a flashlight around the day and night is literally “it is easy to say and difficult to do”, and it is actually the case that immediately after feeling inconvenience due to a disaster, it returns to the original Kiami as time passes It is. The reason for this is that it is not necessary to always have a flashlight around the person, and as things do not happen, they are often gradually abandoned.

  For this reason, various types of flashlights that are easy to carry have been devised, but the points that do not need to be used at all times are the same, and these are also used at the beginning, but in reality they are left unattended over the course of a peaceful day. It is.

On the other hand, mobile phones and the like are always carried around because of the necessity for their use. Therefore, if such a portable terminal has an emergency lighting function, it can be used immediately without being searched in an emergency. However, there are no examples of commercialization of mobile phones with lighting devices so far. Although it is conceivable to use the display surface of the mobile phone for illumination, the display surface is not supposed to function as a light source from the beginning, and is too weak as a light source and is not practical.

The following documents exist in relation to this case.

For this reason, in the illuminating device 2, there is very little possibility that the battery runs out unexpectedly like a conventional flashlight.

FIG. 2 is an explanatory view showing the construction of one embodiment of the lighting device 2. The lighting device 2 is detachably attached to the mobile phone body 1 via a connector R. The power supply circuit is provided with a connector portion 6 so that the power sources of the mobile phone body 1 and the lighting device 2 can be complemented with each other when necessary.
In addition, since the connection tool R should just be able to latch an illuminating device in the place which does not become obstructive, such as a right-and-left or up-and-down edge part of the mobile telephone main body 1, as shown in FIG. )), A sandwiching type (FIG. 3 (b)), a type in which both are connected with a flat fastener (FIG. 3 (c)), and the like. In FIG. 3 (a), the end portion of the mobile phone main body 1 is freely detachable from the fitting portion K in the lighting device 2. In FIG. 3B, the sandwiching portion L of the lighting device 2 grips the end portion of the mobile phone body 1 by spring pressure. In FIG. 3 (c), M is a flat fastener affixed to an appropriate place between the mobile phone body 1 and the lighting device 2, and the lighting device 2 is attached to the mobile phone main body 1 by the contact and separation of both flat fasteners L. It can be easily attached and detached.

In the illuminating device 2 having the connector section 6 shown in FIG. 2, the light source is an LED, the power source is a lithium ion battery, and a charging circuit for the lithium ion battery. That is, FIG. 4 is a block diagram showing an outline of the configuration of such a lighting device 2. That is, in the figure, 7 can be a charging circuit for a lithium ion battery, and switch 5 is a selection for opening and closing the charging circuit 7 for only the lighting device, the charging circuit 8 only for the mobile phone, the charging circuit for both the lighting device 2 and the mobile phone body 1. The switch 5 selects one of them to charge only the power source 4 of the lighting device 2, charge only the power source 8 of the information terminal, and charge the power source of both the lighting device 2 and the mobile phone body 1. Any one can be done arbitrarily.

FIG. 5 is a block diagram showing a configuration of the mobile phone body 1 in which the lighting device 2 is incorporated. In this case, the lighting device 2 does not include a connector portion. That is, in the figure, 7 can be a charging circuit for a lithium ion battery, and switch 5 is a selection for opening and closing the charging circuit 7 for only the lighting device, the charging circuit 8 only for the mobile phone, the charging circuit for both the lighting device 2 and the mobile phone body 1.

Any one can be done arbitrarily.

Note that the selection unit in the switch 5 is configured to charge only the power source of the lighting device, charge only the power source of the information terminal, or supply power to both the lighting device and the information terminal according to the consumption of the power source of either the mobile phone or the lighting device. It may be configured to have a function of automatically selecting one of the charging methods, and the function control is performed by a microcomputer.

FIG. 6 is a view showing another embodiment of a mobile phone provided with any one of the above lighting devices, FIG. 6 (a) is an external perspective view, and FIG. 6 (b) is a front view showing a use state. .
As shown in FIG. 6 (a), the cellular phone main body 1 is composed of a part 1a having a display on the inside and a part 1b having a keyboard on the inside, and 1a and 1b can be folded in two. The mobile phone body 1 is mounted with the illumination device 2 having any one of the above-described configurations, and the condenser lens 3a of the illumination device 2 is set on either the outer portion 1a or 1b.

When the lighting device 2 is used in a hands-free state, as shown in FIG. 6 (b), the portion without the condensing lens 3a is locked and stored in a breast pocket or the like, and the surface of the condensing lens 3a is pocketed. Set outside. In such a state, it is possible to irradiate light in a predetermined direction from the chest without gripping the mobile phone main body 1, and both hands can be used freely.

Note that the lighting device can be easily prevented from running out of battery power by being configured so that the battery can be charged through a charger used in the mobile phone body without having a dedicated charging unit. That is, when the mobile phone body is charged, the battery of the lighting device is also charged together, or only the battery of the lighting device is charged.

The portable terminal with a lighting device according to the present invention can be used in various ways as necessary. For example, it is very convenient to use it as a bicycle lamp. Bicycle lamps often have their generators not working due to aging, and are unavoidably forced to run unlit at night, which is often very dangerous. However, if the portable terminal according to the present application is possessed, it can be sufficiently used as a bicycle lamp as occasion demands.
